I am still looking for a good source for manufacturing data by country and year. Today I found some data from the United Nations Statistics Division. The data for the top five manufacturing economies: China, Germany, Japan, United Kingdom and United States. Figures are in current $US billion. The data used is for Mining, Manufacturing and Utilities (because China and Germany do not have manufacturing data separated out).
For manufacturing output only:
This data shows the United States manufacturing economy is continuing to grow and is solidly the largest manufacturing economy: which contradicts what many believe. It is true manufacturing jobs are decreasing in the United States and worldwide – China is losing far more manufacturing jobs than the USA.
I including some information on the manufacturing economy in my post to the Curious Cat Science and Engineering blog: Phony Science Gap? and referenced my previous post here, Manufacturing and the Economy which reminded me that I wanted some updated data.
